SEED-PLANTER.

SPECIFICATION forming part of Letters Patent No. 369,585, dated September 6, 1887.

Application filed June 30, 1887. Serial No. 242,974. (No model.)

To all whom it may concern:

Be it known that I, JAMns CAMPBELL, a resident of Harrison, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Seed-Planters, of which the following is a specification.

My invention relates to that class of corn planters which employ a rotating plate to drop seed.

The inventionconsists in the construction and combination of devices hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 is a side elevation of my improvement. Fig. 2 is a top plan view ofthe rotating seed-plate. Fig. 3 is a bottom plan view ofthe same. Fig. 4 is a detail view of the parts of the machine. Fig. 5 is a central vertical cross-section through the rotating and stationary seed-plate. Fig. 6 is a detail view of the lock-washer attachment. Fig. 7 is a perspective viewl of the seed-brush.

1 represents the ordinary pilot seed-wheel of a corn-planter, 2, the frame; 3, the colter; 4, the seed-shoe; 5, the coveringshares. All of these parts are old and made in the ordinary way. l

6 represents the handles, which are connected to the frame 2 by means of a standard, 7, by a through-round, 8.

c represents a second hole in the standards 7, for adjusting vthe handles up or down to change their height.

The handles 6 swivel or pivot on the rungS when the nut is slackened, and in order to allow the handles to be raised and lowered directly I have provided the bracket 9, which is provided with a segmental slot,`10, with a fastening-bolt, 11, and the lock-washer 12.

The outer face of the bracket 9 is provided with serrations 13. Similar serrations are formed on the face of the washer 12, and the bolt 11 secures these in any desired position. Thus the rear end of the handles may be adjusted in height by means of this lock-washer and the segmental slot 10 in the bracket 9. In order to further adj ust the position of the handles the bracket 9 is provided with a longitudinal slot, 14, at the base, the face of which is provided with serrations, on which engage a serrated washer, l5. 16 represents a tap for holding the serrated washer 15 upon the serrations ofthe slot 11. Thus 4the bracket 9 may be adj usted forward and back and control the height of the handles.

The seed-drojiiping mechanism is composed of the stationary plate 17, which has an arm, 18, upon each rear corner,extending outward and provided with a gain, 19, which fits into a similar gain in the standard 7. The gain 19 is a little-wider than the standard 7 for two purposes: First, the contraction and expansion of the metal or of the material is inclined to strain the standards. By making the gain 19 wider than the standards all dangerof springing the parts is avoided. Again, when thel seed-planter top tips over and strikes upon the handles 6, it' they are rigid, they are liable to break. This wide gain therefore connects the parts flexibly together.

My improvement in the dropping-plate is constructed as follows:

21 represents a revolving plate, which is provided with gear on the underside, 22, as shown in Fig. 1, and it is driven in the usual Way. 23 represents the ordinary brush placed inside ofthe seedbox21, and rests down upon the top surface ofthe plate 25. In the planting of peas, beans, and even corn the brush is inclined to sweep out the seed from the seedholes b. In order to avoid this and secure a uniform deposit with any desired amount ot' seed, I provide an elongated pocket, 2G, in rear of the hole b, so that as the seed enters the hole b in the plate 21 during its revolutions it will travel back and fill the pocket 26, asindicated at 0, Fig. 3, so that a partial charge of seed is gathered in the pocket c. When this pocket and its openings arrive over the spout 27, the charge contained in said pocket and in the orifice c drops into the spout 27 and is deposited in the ground. Thus I secure a uniform deposit, and by means of this device peas, beans, and other seed easily swept offby the brush can be deposited in regular quantities, thus making a very positive seeddropper.

l Another diiiiculty experienced in the use of brushes is the liability of the bristles to spread apart and the seed to work up in them and the bristles to' wear off uneve'nly, even wheny the brush is adjusted by rotating. I overcome this tendency by providing a iiexible band, 34, which is preferably made of rubber, and

made to clasp around the bristles 32. This holds the bristles from spreading and allows them to yield sufficiently to perform the oiice of a brush. This band canbe raised as the bristles wear and hold them in a vertical position, so that the brush will do its-work much better than when the bristles are not supported by this flexible band.

Having described my invention, 'what I claim is 1. The combination, with the frame of a seed-planter, of the standards 7, the rung 8, thehandles 6, mounted on the rung, the bracket 9 on the frame, having the segmental slot 10, and the bolt 11, passing through the forward ends of the handles and the said slot and vertically adjustable therein, substantially as described.

2. rIhe combination, with the frame of a seed-planter, of the standards 7, the rung 8, the handles 6 on the rung, the bracket 9, having the horizontal slot 14 and vertically-ar- Rranged segmental slot 10, the bolt 16, for adjusting said bracket horizontally, and the bolt 11, passing through the handles and segmental slot and vertically adjustable therein, substantially as described.

3. The combination, with the frame of a seed-planter, of the standards 7, carrying the handles 6, the bracket 9 on the frame, having a vertically-arranged slot, 10, provided with serrated edges, the serrated washer 12, and the bolt 11, passing through the handles, washer, and slot and vertically adjustable in the latter, substantially as described. 1

4. In combination with the frame and handles of a seed-planter, the adjustable bracket 9, provided with a segmental serrated slot, 10, and the longitudinal serrated slot 14, and the lock-washer and bolt for connecting the parts together, substantially as specified.

5. The combination, with the frame and hopper of a seed-planter, of the standards 7 on the frame,having a gain, and the stationary plate in the bottom of the hopper, having the projecting arm 18, provided with a gain, 19, loosely engaging the gain of the standard, substantially as described.

In testimony whereof I have hereunto set my hand.
